Re: LAN flooding

This depends on the platform and the nature of the traffic. If the
traffic is going through a l3 interface, netflow will work. But if it
is intra-vlan that may not be possible. i know the 6500 can do bridged
netflow, see 'ip flow export layer2-switched vlan if such is the case.
The nexus series is also capable of this.
